Phoenix, Arizona Water Quality: What You Need to Know
Phoenix, Arizona, is committed to delivering safe and reliable drinking water to its residents. The city regularly tests its water and publishes a comprehensive water quality report, also known as a Consumer Confidence Report (CCR), annually. This report details the sources of Phoenix’s water, detected contaminants, and how the city ensures the water meets or surpasses all federal and state drinking water standards.
Where Does Phoenix Get Its Water?
Phoenix primarily relies on surface water from the Salt River, Verde River, and the Colorado River. The Salt and Verde Rivers are managed through a series of dams and reservoirs that help to store water and regulate flow. The Colorado River water is transported to Phoenix via the Central Arizona Project (CAP) canal. The city also utilizes groundwater to supplement its surface water sources.
What’s in the Phoenix Water Quality Report?
The annual water quality report provides a detailed breakdown of the substances found in Phoenix’s drinking water. The report typically includes information on:
- Source Water Assessment: Describes the potential sources of contamination in the city’s water sources.
- Detected Contaminants: Lists all regulated and unregulated contaminants detected in the water, including their levels and comparison to established standards. Common contaminants can include things like:
- Microbial Contaminants: Bacteria and viruses that may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.
- Inorganic Contaminants: Salts and metals, which can be naturally occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming.
- Pesticides and Herbicides: May come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses.
- Organic Chemical Contaminants: Synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, and septic systems.
- Radioactive Contaminants: Can be naturally occurring or be the result of oil and gas production and mining activities.
- Compliance with Regulations: Demonstrates that the city adheres to all regulatory requirements set by the Environmental Protection Agency (EPA) and the Arizona Department of Environmental Quality (ADEQ). You can learn more about water quality standards from the EPA.
How is Phoenix Ensuring Water Quality?
Phoenix employs advanced water treatment technologies to ensure its drinking water is safe and meets all regulatory standards. These technologies include:
- Coagulation and Flocculation: Chemicals are added to the water to cause dirt and other dissolved particles to clump together, forming larger particles called floc.
- Sedimentation: The floc settles to the bottom of the water supply, where it can be removed.
- Filtration: The water passes through filters that remove smaller particles that didn’t settle out during sedimentation.
- Disinfection: Chlorine or other disinfectants are added to kill any remaining bacteria or viruses.
